Imvelaphi
I-IWAVE izenzele inkqubo ehlanganisiweyo esekwe kwitekhnoloji ye-LTE, enezibonelelo ezicacileyo kugutyulo lwaselwandle kunye nokusebenza okuphezulu.
Inkqubo ehlanganisiweyo ye-TD-LTE yangaphandle ineengenelo zetekhnoloji yokhuselo lwe-ultra-long, itekhnoloji ye-RRU enamandla amakhulu, itekhnoloji yokunyusa amandla, usasazo olumxinwa losasazo lokuphucula usasazo lwenethiwekhi, inzuzo ephezulu yeCPE, itekhnoloji yonxibelelwano oluphantsi, njl. ukugqunywa kwebhendi yefrikhwensi yokuhlanganiswa komkhosi noluntu.Ngegunya.Ineempawu zokudityaniswa okuphezulu kunye nokugcinwa kwamahhala, okufanelekileyo kwiindawo ezinzima kunye nezinzima, kwaye zibonelela ngokuzinza kunye nokuhanjiswa okuthembekileyo.
Iimpawu zobuGcisa beeMveliso
Itekhnoloji yokugubungela ixesha elide
Ngolungiselelo lwexesha elikhethekileyo, umgama wokugubungela ungafikelela kuma-90km ukuhlangabezana neemfuno zonxibelelwano zolwandle olukufuphi, oluphakathi, nolukude.I-7 ye-subframe ekhethekileyo esetyenziswa ngokuqhelekileyo i-7 (10: 2: 2) inokuxhasa i-15km, kunye ne-5 (3: 9: 2) ye-subframe esetyenziswa ngokuqhelekileyo i-5 (3: 9: 2) inokuxhasa i-90km.Uqwalaselo olugqithisileyo (ilahleko yenxalenye ye-bandwidth), ukucwangciswa kwe-0, kunokufikelela kwi-119km.
Usasazo lomqadi olumxinwa longeza usasazo lwenethiwekhi.
Le teknoloji inokulawula iziteshi, i-PDSCH TM2 / TM3, i-CRS, njl., efanelekile kwiimeko ezinomda we-CRS ophantsi.Ukufikelela kwiindlela ezinde kakhulu kunye nesiqithi esincinci, indawo ekujoliswe kuyo incinci kwaye inokuqwalaselwa ukusetyenziswa.Inokuphuculwa ukuya kwi-CRS malunga ne-50%.
I-CPE ephezulu
Umsebenzi we-CPE wesandisi sesandi esisezantsi songeza ulwamkelo lolwamkelo lwe-LTE.Ixhotyiswe nge-eriyali ye-8db ye-omnidirectional, ngelixa ufumana phantse i-20dbi inzuzo, Ukuphelisa umonakalo wokungena kwe-10 ~ 20db, uphucule ngakumbi umphumo wokufumana, kwaye umgama wokugubungela unokunyuswa nge-150% -200%.Isixhobo i-IP67 ingenamanzi, isondlo-free emva kokufakwa.
Itekhnoloji yokuSasaza amaza aphantsi
Ibhendi ye-frequency 600MHz ibizwa ngokuba yi "digital dividend", enenzuzo yokulahleka kokudluliselwa komqondiso ophantsi, ukugubungela okubanzi, ukungena okunamandla, iindleko zothungelwano eziphantsi, njl. Ngoko ke, ithathwa njengebhendi yegolide yophuhliso lonxibelelwano lweselula.
I-Frikhwensi ephantsi ineengenelo ezininzi zokusasaza, ilahleko ephantsi yosulelo, kunye nokukwazi ukusasazeka kwemitha.Xa kuthunyelwa izikhululo ezininzi, inzuzo yokhuseleko ibonakala.Umzekelo, kwiindawo ezixineneyo ezisezidolophini, inani lezikhululo zokusasaza ezifunekayo kwi-1.4GHz/1.8GHz yi-3-4 ngokuphindwe ka-600MHz, kwaye kwiimeko ezingenanto ezifana namadlelo edolophu okanye iziqithi, liphindwe ka-2-3 inani lokuthunyelwa kwindawo. Ibhendi ye-frequency ye-600M.
Ukuhlanganiswa okuphezulu, ukugcinwa-free
Isixhobo sihlanganiswe kakhulu ngaphandle kokuthunyelwa kwegumbi lomatshini, inkqubo idibanisa izinto eziphambili zenethiwekhi ze-LTE ezifana ne-RRU, i-BBU, i-EPC kunye nezinto ezinjalo, zilungele ukuthunyelwa, kwaye ziyi-zero kwisixhobo se-IPv6 engenamanzi.
Akukho mfuneko yokuthunyelwa kwegumbi lekhompyutha, kwaye izixhobo zihlanganiswe kakhulu.Inkqubo idibanisa i-RRU, i-BBU, i-EPC kunye nezinye izinto eziphambili zenethiwekhi ye-LTE zibe yinto enye, ekulungele ukuthunyelwa.Isixhobo sikwinqanaba lokungangeni kwamanzi IPV6, kwaye akukho londolozo.
Networking Topology Map kolu vavanyo
Inkcazo emfutshane yovavanyo
I-1, Inkqubo edibeneyo ye-TD-LTE yangaphandle yakhiwe kwinqaba yentsimbi okanye isakhiwo esiphakamileyo esikufutshane nesiqithi, kwaye inethiwekhi yoluntu engenazintambo isetyenziswa.
I-router yenethiwekhi yoluntu yi-TD-LTE i-accessory ye-outdoor ehlanganisiweyo yenkqubo, enokuthi ifakwe, inikwe amandla, kwaye ifumaneke kwizikhululo zesiseko sabaqhubi abaninzi ukuqinisekisa ukuzinza kokubuyisela.
I-2, Inkqubo edibeneyo ye-TD-LTE yangaphandle inodibaniso oluphezulu kwaye idibanisa inethiwekhi engundoqo, i-BBU kunye ne-RRU ukuqinisekisa amandla aphezulu-amandla okugubungela indawo ebanzi ngelixa uphucula uzinzo lokusebenza kwezixhobo.Inkqubo edibeneyo isekela i-IP67 engenamanzi kwaye ivumelanisa neendawo ezinzima kunye nemozulu embi.
3, Inkqubo yokudibanisa yangaphandle ye-TD-LTE kunye neCPE zigutyungelwe yibhendi yefrikhwensi yomkhosi-yasekuhlaleni (ama-566-606 amanqaku aphindaphindiweyo).Ukulahleka kwendlela ye-low-frequency space incinci, kwaye ukuhanjiswa okunamandla okungafaniyo kuqinisekisa i-bandwidth kunye nokunyuka komgama wokugubungela.
I-4, i-CPE ye-IP67 ye-industrial-grade ayinamanzi, iqhelanisa nemekobume yangaphandle enzima, kunye nomgangatho we-industrial-grade uphucula i-bandwidth kunye nokuzinza.Ukusasazwa okudityanisiweyo kunye nonikezelo lwamandla ngezixhobo zemozulu.
Iziphumo zovavanyo lokhuseleko lwaselwandle.
Izixhobo zisekwe kwisakhiwo esiphakamileyo seDishui Lake eShanghai, esivavanya iPort yaseYangshan kunye neHangzhou Bay ngokulandelanayo.Isikhululo sesiseko sisetyenziswe ngexesha kunye ne-tripod pole (33m ngaphezu komphakamo wolwandle), kwaye umgama wovavanyo oluphezulu yi-54km.
Amandla omqondiso we-CPE-74, ifowuni ephathwayo (200mw) ukufikelela okuqhelekileyo, ishishini eliqhelekileyo, ividiyo ecacileyo kunye negudileyo.Iimfuno zeprojekthi ngelo xesha ziye zahlangatyezwa, kwaye uvavanyo olongezelelweyo aluzange lwenziwe.Inokufikelela ngokuqhubekayo ukugubungela amanzi eSiqithi saseYangshan kunye neChibi laseDrishui.
